摘要:
基于 Landsat 8 影像数据,对东莞市松树林 (Pinus sp.)、杉木林 (Cunninghamia lanceolata)、针 叶混交林 3 种针叶类森林生物量进行估算,利用相关分析、主成分分析和逐步回归分析,建立针叶类森 林生物量遥感估算模型,其决定系数 (R2) 值分别为 0.880 9、 0.832 5、 0.964 0,均达显著水平。经适用性 检验,模型均达 0.05 显著水平,可用于东莞市针叶类森林生物量估算。

Abstract:
Based on Landsat 8 image data, this paper estimates the biomass of three coniferous forest in Dongguan, including Pinus forest, Cunninghamia lanceolata and coniferous mixed forest . By using correlation analysis, principal component analysis and stepwise regression, a remote sensing estimation model of coniferous forest biomass was established, and its determining coefficient (R2) value were 0.880 9, 0.832 5 and 0.964 0 respectively, which reached a significant level. The applicability test showed that the model reached 0.05 significant levels and could be used for estimating the biomass of coniferous forest in Dongguan.
